Sorry, the range prohibits taking pictures, so this one was taken "illegally" with a phone in low lights just so I can at least remember what I was shooting. However, as I stated above, I will go back next time and ask them to show me all their rentals .38/357 which basically consists of three or four very similar SW, one of which is 7 shot.

Thank you for all your help guys, I learn something new every day. And yes, now I know where the model number is, I learned it on my last visit: it's on the lug hidden, until you open the cylinder.
